Description

Technical Field

[0001] This utility model relates to the field of tractor clutch housings, and in particular to an improved housing for a tractor clutch. Background Technology

[0002] The tractor clutch is primarily used to connect and disconnect the engine and transmission, enabling operations such as starting, shifting gears, and stopping the tractor. The clutch is essential for the proper starting and shifting of the tractor; and the clutch requires a housing for installation. The housing protects and secures the clutch.

[0003] The housing of an existing tractor clutch includes a housing for connecting the belt and the release pawl, and a side cover for enclosing the clutch inside the housing. The side cover and the housing need to be fixed together with bolts. However, due to the high overall vibration intensity of the tractor during startup, and the bolts used to connect the side cover and the housing lack a limiting structure, the bolts used to connect the housing and the side cover are prone to rotation and loosening under long-term use in a vibrating environment.

[0004] To address the aforementioned problems, we propose an improved housing for a tractor clutch. Utility Model Content

[0005] The purpose of this invention is to provide an improved housing for a tractor clutch, which has the advantage of limiting the fixing bolts connecting the housing and the side cover.

[0006] The above-mentioned technical objective of this utility model is achieved through the following technical solution: an improved housing for a tractor clutch, comprising a housing, an inner side cover plate provided inside the housing, six fixing bolts threaded inside the side cover plate, anti-rotation blocks sleeved on the surface of the fixing bolts, a connecting bracket fixedly connected to the anti-rotation blocks on one side of the side cover plate, a connecting ring fixedly connected inside the connecting bracket, and a connecting spring installed between the connecting ring and the side cover plate; it should be noted that the tractor clutch is prior art and its working principle will not be described again, and the clutch is not shown in the figure.

[0007] By adopting the above technical solution, by setting an anti-rotation block, a connecting bracket, a connecting ring, and a connecting spring, the anti-rotation block is fitted onto the surface of the fixing bolt, and the connecting spring limits the position of the anti-rotation block, which can ensure that the vibration of the tractor during operation will not cause the fixing bolt to rotate and loosen; and by pulling the connecting ring outward, the connecting ring drives the connecting spring to extend, allowing the anti-rotation block and the fixing bolt to separate, which can facilitate the disassembly of the fixing bolt by the staff.

[0008] The present invention is further configured such that: the side of the connecting spring near the side cover plate is fixedly connected to the side cover plate by a spring fixing member, and the side of the connecting spring near the connecting ring is fixedly connected to the connecting ring by a spring fixing member.

[0009] Using the above technical solution, by setting up a connecting spring, and by fixing the spring fixing component to the connecting ring and the side cover plate respectively, the connecting ring and the connecting spring can be connected; it should be noted that... Figure 2 When the connecting spring is in its normal state, it vibrates when the tractor is working without any external force pulling it outward. The maximum extension length of the connecting spring does not exceed the length of the left rod head of the fixing bolt.

[0010] The present invention is further configured such that: a bolt mounting seat is fixedly sleeved on the inner wall of the outer shell, and the interior of the bolt mounting seat is threadedly connected to six fixing bolts.

[0011] By adopting the above technical solution, the bolt mounting seat is set up for threaded connection with the fixing bolt, thereby facilitating the fixing bolt to pass through the side cover plate and connect with the bolt mounting seat to limit the side cover plate.

[0012] The present invention is further configured such that: a spring mounting groove is provided on one side of the inner cavity of the outer shell, and the number of the spring mounting grooves is at least six.

[0013] The above technical solution uses a spring mounting slot to install the spring of the limit clutch.

[0014] The present invention is further configured such that a release bearing is fixedly sleeved inside both the outer shell and the side cover plate.

[0015] By adopting the above technical solution, the interior of the separation bearing is used to connect with the separation shaft.

[0016] The present invention is further configured such that: a through groove is provided inside the connecting ring, and the diameter of the through groove is larger than the diameter of the release bearing.

[0017] By adopting the above technical solution, the through groove is designed to facilitate the worker's fingers to pass through the through groove and then pull the connecting ring from the inside to the outside.

[0018] In summary, the present invention has the following beneficial effects:

[0019] This invention utilizes a connecting spring to connect the connecting ring and the side cover plate. The connecting ring connects to an anti-rotation block that engages with the head of a fixing bolt. The connecting spring limits the connection ring, connecting bracket, and anti-rotation block, preventing the fixing bolt from rotating. This prevents vibrations generated during tractor operation from causing the fixing bolt to rotate and loosen, ensuring a tight connection between the side cover plate and the outer shell. Furthermore, by connecting the connecting spring to the connecting ring and the side cover plate, when removing the fixing bolt, pulling the connecting ring extends the connecting spring, causing the anti-rotation block to separate from the fixing bolt, thus not hindering maintenance personnel's disassembly and installation operations on the outer shell.

[0024] The present invention will be further described in detail below with reference to the accompanying drawings.

[0025] Example 1:

[0026] refer to Figure 1 , Figure 2 and Figure 3An improved housing for a tractor clutch includes a housing 1. Inside the housing 1 is a side cover plate 2. Six fixing bolts 3 are threadedly connected to the inside of the side cover plate 2. Anti-rotation blocks 4 are fitted onto the surfaces of the fixing bolts 3. A connecting bracket 5, fixedly connected to the anti-rotation blocks 4, is located on one side of the side cover plate 2. A connecting ring 6 is fixedly connected inside the connecting bracket 5. A connecting spring 7 is installed between the connecting ring 6 and the side cover plate 2. The connecting spring 7 connects the connecting ring 6 and the side cover plate 2. The connecting ring 6 connects to the anti-rotation blocks 4, which are used to engage with the rod heads of the fixing bolts 3. The connecting spring 7 limits the connection between the connecting ring 6, the connecting bracket 5, and the anti-rotation blocks 4. By limiting the anti-rotation blocks 4, the anti-rotation blocks 4 prevent the fixing bolts 3 from rotating, thus preventing the fixing bolts 3 from rotating or loosening due to vibrations generated during tractor operation. This ensures a tight connection between the side cover plate 2 and the housing 1. Furthermore, by connecting the connecting ring 6 and the side cover plate 2 via the connecting spring 7, when the fixing bolt 3 is removed, the connecting ring 6 can be pulled to extend the connecting spring 7, thereby causing the anti-rotation block 4 and the fixing bolt 3 to separate, thus not affecting the disassembly and installation operations of the housing by maintenance personnel.

[0027] Furthermore, the side of the connecting spring 7 closest to the side cover plate 2 is fixedly connected to the side cover plate 2 via a spring fixing member, and the side of the connecting spring 7 closest to the connecting ring 6 is fixedly connected to the connecting ring 6 via a spring fixing member. Through the arrangement of the connecting spring 7, and the spring fixing members respectively fixing the connecting ring 6 to the side cover plate 2, the connecting ring 6 and the connecting spring 7 can be connected; it should be noted that... Figure 2 When the connecting spring 7 is in its normal state, it vibrates when the tractor is working without any external force pulling it outward. The maximum extension length of the connecting spring 7 does not exceed the length of the left rod head of the fixing bolt 3.

[0028] Furthermore, the inner wall of the outer casing 1 is fixedly fitted with a bolt mounting seat 8. The bolt mounting seat 8 is threadedly connected to six fixing bolts 3. The bolt mounting seat 8 is used to thread-connect with the fixing bolts 3, thereby facilitating the fixing bolts 3 to pass through the side cover plate 2 and then thread-connect with the bolt mounting seat 8 to limit the side cover plate 2.

[0029] Furthermore, a spring mounting groove 9 is provided on one side of the inner cavity of the outer casing 1. The number of spring mounting grooves 9 is at least six. The spring mounting grooves 9 are used to install the spring of the limit clutch.

[0030] Furthermore, both the outer casing 1 and the side cover plate 2 are fixedly fitted with release bearings 10. Through the setting of the release bearings 10, the interior of the release bearings 10 is used to connect with the release shaft.

[0031] Furthermore, a through groove 11 is provided inside the connecting ring 6. The diameter of the through groove 11 is larger than the diameter of the release bearing 10. The through groove 11 allows the operator to pass their fingers through the through groove 11 and then pull the connecting ring 6 from the inside to the outside.

[0032] Brief description of usage: Tractor vibration is mostly up and down. By using the anti-rotation block 4 on the surface of the fixing bolt 3, the separation of the anti-rotation block 4 and the fixing bolt 3 caused by the up and down vibration of the tractor can be avoided.

[0033] When a traditional tractor vibrates, the fixing bolt 3 may rotate due to the vibration, causing the bolt mounting seat 8 or the side cover plate 2 to separate. However, by setting a connecting spring 7 to connect the connecting ring 6, and the connecting ring 6 to connect the anti-rotation block 4 sleeved on the surface of the fixing bolt 3, the anti-rotation block 4 can limit the fixing bolt 3, preventing it from rotating under the vibration of the tractor. This restricts the threads of the fixing bolt 3 and the side cover plate 2 to the bolt mounting seat 8 from loosening, thus ensuring the stability of the connection between the fixing bolt 3 and the side cover plate 2 and the bolt mounting seat 8.

[0034] For the installation and removal of fixing bolt 3, the operator can pull the connecting ring 6 to extend the connecting spring 7 and separate the anti-rotation block 4 from the fixing bolt 3. The operator can then use a wrench to remove the fixing bolt 3. If the fixing bolt 3 is to be installed, the threaded end of the fixing bolt 3 can be passed through the inside of the anti-rotation block 4 and the side cover plate 2 to connect with the bolt mounting seat 8. Once the head of the fixing bolt 3 reaches one side of the anti-rotation block 4, pull the anti-rotation block 4 through the head of the fixing bolt 3 and continue to install the fixing bolt 3.

[0035] This specific embodiment is merely an explanation of the present utility model and is not intended to limit the present utility model. After reading this specification, those skilled in the art can make modifications to this embodiment without contributing any inventive step, but as long as they are within the scope of the claims of the present utility model, they are protected by patent law.
